I To aZlwhom-it mdylconcem:

Be it knownv that I, WALTER Soo'rr DoE, a citizen of the United States,and a resident of Jersey City, in the county of Hudson and State of NewJersey, have invented new and useful Im rovements in Dry-Battery Cells,of which tli I act description.

and to render the same very effective at all The invention relates toelectro chemist'ry, and its object is to .provide'certain 'ne'wanduseful improvements in dry battery cells, whereby the exciting fluidusually discharged from the battery filling when the battery is in useisstored' and reused injan'eflective manner, to increase thelifeofthebatte'ry times.

The invention consists of novel features and parts and combinations" ofthe same, which will be more fully described hereinafter and thenpointed out in theclaims. p A practical embodiment of the invention isrepresented in the accompanying" drai'vings forming a part of thisspecification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a sectional side elevation of the improvement; Fig. '2 is aplan view-of the reservoir; and Fig. 3 is an inverted'plan view of thesame. "In dry battery cells 'as heretofore constructed, the lifeof thebattery is'shortened and its eflicacy isreduced, owing to the escape andwaste of exciting fluid liberated within the cell from the batteryfilling at the time the battery is in use, or the temperature of thebattery is raised by a rise in temperatureof the-surrounding air, Inorder to prevent the esoa e of the excitant thus liberated within the coland to efiectively reuse the,

eXcitant, the following arrangement ismad e The inlosing electrodeA, ofthe dry -bat' tery' cell is made in the form of a zinc can having alining B, of paper or other bibulous inclosing electrode A, as plainly-illustrated e following is \affull, clear, and exbibulous material, andthe top of the reservoir F and the washer (S are sealed in the" upperend of the in'closing electrode A by theusual seal H of wax or othersuitable material; The reservoir F is preferably made of two cup shapedannular members F andlF :of.

'w ich the top member'F is inverted and fits into the. bottom-memb'er Fas plainlyshown in 'Fig, 1, and the bottom member h? of the reservoir Fis provided with openings F-"a, to v permit the exciting fluid risingfrom the ,fill

when the b'atteryris not in use, thepr' viously'" collected excitingjfiuidgflows out of the reservoir F onto the lining B, thus moisteriingthe same, to insure the proper cohductivity.- thereof.- It will furtherbenotic'ed that by.

having thewasher G, the latter is moistened by the lib'eratedfluidi Thebibulous washer. G takes up the superfluous moisture previous tothesealing in of" the reservoir ,F, and the moisture thus taken up'bythe Washer ex- --cites tl1'e zinc surface of the reservoir body,

thereby assuring additional amperage.

" The top member F: of the reservoir F is provided with a vent hole F'normally'o en,

and adapted to be. closed by a'valve are ranged within the reservoir F;Thus in case the battery cell is placed'upsidedown after use, the valveI closes the vent opening F so that the exciting fluid collected in thereservoir F is 'retained therein and not lost.

By the use of the improvement described; f more excitant can be put inthe cells without leakage, as the reservoir takes care of any ex -ces'sexcitant"which is returned to the'linin'g material, and which containsthe usual iillingmaterial C, packed around the inclosed elec-,;;trodezD'iof carbon or'other suitable material: A bushing E', -of rubbervor other suitable insulating material, surrounds the electrode D;

near the upper end thereofgandthis bushing; surrounded by anannulanreservoir preferably made of zinc, contact with the and fillingof the cell,- for re-use in the manner described;

Having-thus described} my invention, I

claim a'sjnewg and desire to secure by L'etters A rybattery f rovidedwant reservoir inade'o'f zinc, see ed means for the' excitant lilmratedifrom the in the top ofthebattery and insi lated'fro'm'thecarbonelectrode, the said reservoir bein ,in'contact with thejih f-closin'gelectrode '0 the battery andfhaving battery filling to passinto the said reservoir and to be returned to the lining of theinclosing electrode of the battery.

2. A dry battery provided with a reservoir sealed in the top of theinclosing electrode and in contact therewith, an insulating bushingsurrounding the inclosed electrode and surrounded by the said reservoir,and a washer I of bibulous material on the under side ol the reservoir.

4. A dry battery provided with a reservoir sealed in the topol' theinclosing electrode and in contact therewith and formed of twocup-shaped annular members, of which the topniember is inverted and fitsinto the bottom member, and the latter is provided with l openings forthe passage of the moisture discharged from the battery filling.
